Abstract
Disclosed are methods, apparatus, and computer-readable storage medium for entropy/decoding contexts for intra prediction modes in video encoding/decoding. An example method includes receiving a video bitstream that includes a current block and deriving a first context used to entropy encode a set index based on coded information. The coded information comprises at least one of: information of the current block, and mode information of at least one neighboring block of the current block. The method further includes deriving a second context used to entropy encode a mode index for the current block based on the coded information, entropy decoding the set index according to the first context, and entropy decoding the mode index according to the second context. The method also includes determining the intra prediction mode for the current block based on the set index and the mode index.
